Find the sum: 4 radical 3 + 11 radical 12

Ksenya-84 [330]

Answer:

$26\sqrt{3}$

Step-by-step explanation:

We want to find $4\sqrt{3} +11\sqrt{12}$ . $11\sqrt{12}$ can be written as $11\sqrt{4*3}=11*\sqrt{4} *\sqrt{3}=11*2*\sqrt{3}=22\sqrt{3}$ , so we can now write our original equation as: $4\sqrt{3}+22\sqrt{3}$ .

We can combine like terms: $4\sqrt{3}+22\sqrt{3}=26\sqrt{3}$

Hope this helps!
